New to me yesterday. Manufacturer’s cosmetic restoration with new wiring harness, starter, alternator, all tune items. Outdrive and engine removed for restoration. Outdrive gone through.
The motor died several times today after restarts with the blower on. The blower died too and then restarted as if a breaker had reset. Turned the blower off and no more problems. Neglected to try to recreate. Ideas?
Sounds like it's been wired the way I strongly discourage. Anything that isn't engine should be coming off a COMPLETELY separate power supply system. The engine electrics and the 'boat' electrics should have only the battery and the battery switch in common.
The only way to resolve your problem properly is a rewire that takes anything that isn't 'engine' off the engine electrics. Somewhere someone will have run a fuse panel or a terminal block off the main power feeding from the engine to the instrument cluster. Such a bad idea!
Get a length of 6mm (or 8mm) twin (red and black) and run it from the battery switch to a pair of terminal blocks up under the dash (or somewhere else convenient), then run all your lights, blowers, bilge pumps, echo sounders, radios, GPSs and whatever else isn't part of the 'engine' from there. The only things I run on the engine circuit that isn't 'engine' are the hour-meter and the fuel gauge... EVERYTHING else gets run from those terminal blocks. As well as being easier to do that way, it's easier to fault-finder if you do have a problem, but more importantly, an 'accessory' issue isn't going to leave you with a dead engine, and a dead engine will leave you with radios to call for help....
p.s. Can I add a sig line?
Yes. Just go into your profile and hunt around, it's a bit hidden...
